The cave is beautiful, and since it's the off-season, it's deserted, allowing for a leisurely visit. A visit takes about 3 hours, with many steps! Whether it's tiring depends on your physical condition; I personally didn't find it too strenuous. It's not cold inside the cave; a base layer and a sweatshirt are usually enough (in November). The only problem is transportation within the scenic area. There are very few direct buses from the high-speed rail station to the scenic area—only one per hour, and they're very slow. We had to take a taxi, which cost 120 yuan and took 40 minutes. By the time we finished our visit, it was almost dark, and there were no taxis available, especially in the middle of nowhere. I hope the scenic area can change the time of the last bus; otherwise, we would miss our high-speed train back to Guiyang. Finally, a kind man took us to the high-speed rail station. What a thrilling trip!
